FASTENER FOR EYEGLASSES.

Specification of LettersPatent.

Patented Oct. 16, 1906.

Application filed January 11, 1906. Serial No. 295564 To all whom, itmay concern:

Be it known that I, DALLTOR WALDEMAR KOLLE, a citizen of the UnitedStates, and a resident of Portland, in the county of Multnomah and Stateof Oregon, have invented a new and Improved Fastener for Eyeglasses,

' of which the following is a full, clear, and exact description.

This invention relates to fasteners for eyeglasses or'spectacles.

It is especially useful in connection with the construction ofeyeglasses for making a simple connection between the lens, the bow orspring, and the nose-guard.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompany ing drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both views.

Figure 1 is a front. elevation showing the fastener, certain parts beingbroken away and represented in section. In this view the nose-guard isshown complete, while the bow or spring and the lens are represented asbroken away. Fig. 2 is a perspective representing the parts which formthe fastening in the act of being assembled.

Referring more particularly to the parts, 1 represents the inner portionof the lens, which is attached in any suitable manner, such as thatshown, to a post or stud 2. This post 2 is substantially circular incross-section and enlarges toward its outer extremity, where it isformed into an angular socket 3. This socket is preferably rectangularin form and is open above and below. The bow or spring 4 of theeyeglasses is formed withthe usual shank or straight extension 5 nearthe lens 1, and near the lower extremity of this extension, as shownmost clearly in Fig. 2, a round opening 6 is made, said opening beingconnected with the lower extremity of the extension 5 by means of a slot7 as illustrated. This extension 5 is adapted to be shoved down into theupper-extremity of the socket in the manner indicated in Fig. 2, so thatits outer face rests against the outer face or wall 8 of the socket 3.In this way the opening 6 may be brought into alinement with a threadedbore 9, which is formed in the stud 2 to receive a clamping-screw 10,and the outer wall 11 of the socket 3 is formed with an enlarged openingto receive the head of this screw, as

- indicated most clearly in Fig. 1.

lower edge of the wall 8 of the socket 3 I provide a slot 12, which whenthe extension 5 is in position comes substantially into alinement withthe slot 7 of the extension.

The nose-guard 13 is formed with an up wardly-projecting flat extensionor arm 14, which is formed with an opening 15, as shown. This arm 14 isadapted to be inserted in the socket 3 from below, so that the opening15 may be brought into alinement with the opening 6 and the bore 9. Uponthe outer face of the arm 14, just below the opening 15, I provide aninwardly-projecting lug 16, and this lug is of such a width as to fitneatly into the alining slots 7 and 12. When the parts are broughttogether in the manner illustrated and securely fastened by means of thescrew 10, they will evidently not only be pressed together firmly, butthe bow 4, as well as the guard 13, will be locked against rotation uponthe axis of the screw by reason of the lug 16. In this connection itshould be understood that the lug 16 is of sufficient length to ex tendcompletely through the slot 7, its outer edge being received in the slot12.

In order to increase the rigidity of the joint as respects the guard 13,the side edges'of the arm 14 thereof are provided withlaterallyprojecting nibs or shoulders 17, which engage the lower edge ofthe socket 3 on opposite sides. These nibs or shoulders 17 also operateas stops, so as to facilitate the alinement of the opening 15 with thebore 9 when assembling the parts. The head of the screw 10 is formedwith a slot 18 to receive the tip of a screw-driver, as will be readilyunderstood.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a fastener of the class described incombination, a stud adapted to be attached to a lens and having atransverse socket formed therein, a bow having a shank passing,downwardly into said socket, a guard having an arm passing upwardly intosaid socket,
